c) Documentation for individual applications like a
paper mill or the
airport information system that don't exist anymore.
There is the possibility that the industries that these applications
were made for probably have historic groups themselves, and they might
be interested.
For example, if one of us were to find software, or even unit record
procedures, about how the railroads dealt with car classification, I
know of a couple of train geeks that sure would like to have it.
